I received a 20 gallon tank as a gift.  I have had fish in it for about
a year and a half now with no problems.

Wednesday morning I came out and found all the smaller fish dead!
While checking out the tank I found the thermometer read 100 degrees
F.!  I have three fish left, two angels, each about 3 inches, and a
placostamus (sp?) about 5 inches long.  I don't know whether it was
their size or species that enabled them to withstand the temperature.
All the smaller fish, mostly tetras plus a glass cat and an albino cat
died.

The tank heater is a 250 watt model which seemed high to me but is what
the pet store recommended.  It has held the tank temperature constant
within a few degrees (~75F.) for over a year now.  I realize thermostat
contacts can stick but this is unacceptable.  Does anyone have any
ideas that can prevent this from happening again?
